A low pressure trough lingers over northeastern parts of SA this evening. A strong high pressure system moves into the Bight from the west on Saturday, pushing the trough out to the far northeast, with a south to southeasterly flow developing across the entire state by Sunday. The high continues to move eastwards, maintaining a ridge over southern parts on Monday and Tuesday, as the trough begins to move back into the northeast.
